Abstract Details

Purpose:

To evaluate the changes in relative pachymetry and asphericity after myopic excimer laser refractive surgery

Setting:

Kudret Eye Hospital

Methods:

he Intralase femtosecond laser (AMO Inc, Irvine, CA) was used to create the flap in all eyes that underwent LASIK. All eyes underwent LASIK with Zeiss MEL-80 excimer laser for the correction of myopia or myopic astigmatism. 32 eyes of 16 patients were included in the study. The minimum required follow-up was 6 months after LASIK. Each eye was evaluated by Scheimpflug camera imaging (Pentacam, Wetzlar, Germany). Relative pachymetry and asphericity values were analyzed and compared.

Results:

The mean relative pachymeter significantly decreased from -0.8 ± 0.2 (0.1 to -0.9) µm before surgery and -3.4 ±1.1 µm after surgery. The mean asphericity with q value was significantly increased from -0.17 ± 0.11 preoperatively to 0.38 ± 0.39 postoperatively . There was a significant correlation between the achived correction and decrease in relative pachymeter and also between inrease in asphericity.

Conclusions:

The relative pachymeter decreases and the asphericity increases after myopic refractive excimer laser surgery. FINANCIAL DISCLOSURE?: No
